SPECIFICATION forming part of Letters Patent No. 319,725, dated-June 9, 1885. Application filed November 25, 1884. (No model.)

To all whom it may concern:

Be it known that I, J AMEs A. J OHNSON, of Charlestown, in the county of Clarke and State of Indiana, have invented certain new and useful Improvements in Land-Rollers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a top view of my improved land-roller.' Fig. 2 is a transverse vertical sectional view of the same. Fig. 3 is a longitudinal vertical sectional view, and Fig. 4is a detail perspective view.

The same letters refer to the same parts in all the figures.

My invention has relation to land-rollers, and contemplates certain improvements on the land-roller for which Letters Patent. No. 288,061 were granted to me on the 6th day of November, 1883; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the drawings hereto annexed, A designates the frame of my improved land-roller, which is rectangular in shape, and provided at the front with a tongue, B, attached by means of braces G, or in any suitable manner. The said frame is provided with a central division-bar, D, the sides of which have conical bearing-studs E E, provided with cylindrical bearings for the ends of the axles F F, the outer ends of which are journaled in suitable bearings, G G, in the outer or side beams of the frame. Upon the revolving axles F F are journaled the rollers H H, the ends or heads of which are constructed of open-work castings I I, and the bodies of which consist of cylinders of wrought or cast iron, as shown at J J. The inner castings, I, have hubs K, provided with cylindrical extensions L, surrounding the conical bearing-studs E, and the hubs M of the outer castings are provided with set-screws N, by means of which they may be secured upon their respective axles. It will be seen that by this construction, while the rollers are capable of revolving upon their axles, they may also be fixed upon and caused to revolve with the said axles,

the lowest point, where their influence will be most efficiently exercised.

Fromethe foregoing description, taken In connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood. The construction is simple and inexpensive. The rollers are capable of lateral adjustment in the manner and for the purposes described, and they may be caused to revolve with or upon the axles, as may be desired.

I am aware that it is not broadly new to have conical sleeves or thimbles around the ends of an axle or shaft fitting into conical recesses in the hub of a wheel or roller revolving upon the said axle or shaft, and I do not wish to claim such construction, broadly; but

Iclaim- In a land roller, the combination of a frame, a division-bar having conical bearingstuds with cylindrical bearings for the inner ends of the axles, the side beams having boxes or bearings in their inner ends for the outer ends of the said axles, the axles journaled in the bearings of the division-bar and the outer frame-beams, and the rollers, the inner heads or ends of which are provided with cylindrical collars engaging the conical bearings of the division-bar, and the outer ends of which have set-screws for adjusting the rollers upon the axles, substantially as and for the purpose herein set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

JAMES A. JOHNSON.
